To all 't0/tom t may concern:

13e it known that l', ALLEN B. MAULL, a citizen oit the iUnited States, residing at laltimore, in the State of lvlaryland, have invented certain new and useful Improvements in Guide apparatus, of which the following is a specification. y `',lhis invention `relates to an improved guide chart ormap and holder therefor.

`@ne of the objects ofthe invention is tor `:ncoinpanying drawing illustrates the inventive idea wherein, y y

` Figure 1, shows a face viewl ont the chart or gl'lide and the holder. Fig. 2, illustrates the same partly in side elevation. and partly in verticalei'oSssection. Fig. 3, shows an enlarged sectional detail through the central portion o1 the holder' and shows the means Alor holding the chart or map proper in place. F et, illustrates an enlarged detail o1 the radially-sliding scale bar and the connection ci the same `with the holder, and

Fig. 5, shows an enlarged cross-sectional detail through the scale bar to illustrate the sliding and pivoted connection oi the extension arm therewith.

Referring to the drawing by numerals, l, designates a bracket or disk which may be attached to the licor, dash or other desirable part ezt a vehicle such, for example, as an automobile,-the bracket or dislr having suitable perforations, Q., therein `for Vbolts or screws. At one side the bracket or disk is provided with suitable spaced-apart lugs, 3, between which one end of a post or support, Ll, extends and a clamping bolt and nut, 5, serves to adjustably clamp the post to the lugs. A rod, 6, telescopically `engages the post, l, and a clamp, 7, serves to bindthe two together` after a longitudinal adjustment oit them has been made. i The upper end ot the rod, 6, isprovided with a clamp head, `8, which pivotally sustains ashort arm, 9, and

in the adjusted position whilea set-screw,

11, rigidly binds the head to therod, 6, Bv i means ofthe construction set :torth the post, ll, Vmay be swung with respect toblacket dish, 1; rod, G, may be adjustedin poste,

and arm, `9, may be tilted with respect t0 i: rod, .6. plate,-12, has a stud,`13, at `one side which enters" a socket, 14:, in the `outer `end of arm, 9, and is held therein by a` set screw, 15, and at the, other side said plate has a. `centering pin, 16, `whichprojects outi wardly therefrom, as clearly shown` in Fig. 3. The pin, 16, and plate,12, sustain acircular holder, `17, `which latter has aprim `iange, 18,

holder proper, and the rim-flange,`18, of the holder is provided at intervals with circum- A .flerential slots,20, through which the corners, Q1, of a sheet guide, mapyor` chart, 9.2, may be projected while `the `body of` the guide will lie against said holder. `A `scale bar, 2.3, extends,diametrically `across `the holder, 17, said bar being providedwith a circular head, 211.-, with a socket,`25, in `its innerside,-the head being so positioned on `"'l j with an inturned` edge, 19, which overlies the ,the scale "bar that its socket .will register with the central pin,1(. A perforation, .26,` is provided in the center of the guide or chart through which the pin, 16, lnojeets.`

The scale bar, 23, carries a hinge clip, 2T, at one end,-thehinge forming a pivot for the bar to swing on and the clip `servingto slidably connect the hinge with the riignfliange, 18,01v the holder. By means of this construen tion the scale bar is slidably connected at one end to the rim flange of the holder and is also hinged at the same end `so as tosswing 1toward and from the holder. The opposite end of the scalehar, 23, is provided with an outwardly-bent portion, E28, which projects beneath the inturned edge, 19. of the rim y flange and serves to hold said bar in a clamped position `over the guide or chart. Obviously by bowing or pulling the scalebar outwardly at thecenter the` freeend, 28,

will become disengagedwfrom the rim-ange whereupon the bar may be swung outwardly on the hinge, as shown in broken linesin Fig. 2, and the guideor chart, 22, may then be removed or inserted as desired.

The .scale bar, as itsname implies, `is provided witha scale, 29, the object of which will presentlybeiset forth. A head, 30, `is slidably mounted on the `scalej bar tand', a scale arm, 31, ispivotally connectedto the head and extends laterally therefrom. In

the present instance a longitudinal slot, 32, is provided on the scale bar and the head has the form of a clip which passes through the slot and has its two ends bent laterally so as to project over the scale bar and form apivot connection for the end of scale arm, 31, as shown "in detail in Fig. 5. It will thus be seen that the scale bar is 'sustained so as to turn from a central point on the guide or chart and that the scale arm is conneeted to said bar in such a way that its connected-end may be moved longitudinally on the bar toward or from the center of the guide.

In the presentinstance the scale bar has a compass, 32, which is attached to the head, 24, at the center ofthe guide -or chart which enables the points of; the compass to be readily ascertained when viewing the guide. The guide, chart or map is also provided with signs or ma'rl'sy as 'shown at, 33, to indicate compass direction thereon.

The guide or-map, Q3, shown in the present 'example is illustrative of the State of Maryland as an example, and the city of Baltimore, is located as the central point from which the scale-bar, 23, operates If it is desired to determine the 'distances from Baltimore to Annapolis and then from Annapolis to lVashington the scale bar will be turned so that the slotted end thereof will extend radially from the center or Baltimore and project vacross Annapolis; thel head, `3`O,`fwill then be moved along the scale bar'until it will have position over Annapolisand the pivoted scale-arm, 31, will then 1 be l swung so as to extend from Annapolis a to Washington. Thus it will be seen that the distance from Baltimore to Annapolis may be read on the radial scale bar and the "distance from Annapolis to vVVfashington will i y be read on the scale 4arm, 31.
